IMPROVED METHOD 0F CONSTRUCTING THE ACID-CHAMBERSv 0F SODA-WATERAPPARATUS.

Specification forming part of Letters Patent No. 49,871, dated Septemberl2, 1865.

To all whom it may concern.:

Be it known that I, WILLIAM GEE, of the city, county, and State ot NewYork, and a citizen ot' the United States, have invented a new Mode ofMaking and Lining Acid-Chambers or Vessels to hold Acid for Soda-WaterApparatus or Generators; and I do hereby declare that the following is afull and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

To enable others skilled in the art to use my invention, I will proceedto describe its oonstruction and operation.

A is the acid chamber or vessel to hold the acid; B,tl1elining,ofsheet-lead; G, the valve# seat. D is the bottom flange of theacid-chamber A, and E is the top flange. F is the ange that is connectedto a generator or soda-water apparatus. G is the top of acid-chamber. His the stuffing-box to make a tight joint around the valve-rod I. I isthe lead valve, which is taper at the bottom to 'tit into the valve-seat(l, to regulate the tiow ot' acid to the generator. J is the lever toraise the valve l. K is a wrench to unscrew the stuffing-box H when thevalve is to be raised. This releases the packing and lets the valve riseeasy. The stuffingbox H is packed with rubber, so that when the wrench Kis turned to unscrew the box the rubber is released. and then there isno friction, but when the box is screwed tightit makes a friction on therod and prevents the rod or valve from rising.

In all other chambers the box is packed with cotton or hemp, and it mustbe screwed so tight as to allow the rod or valve to play up and down,and sometimes the valves will blow up and let the acid all down, andthen the machine is liable to burst; but with the stuffing-box packedwith rubber, and the wrench to tighten the stuftingbox when the valve isdown, it cannot rise, as the rubber will make so much friction it wouldbe impossible.

In all other acid chambers or vessels the outside chamber is lined withlead in such a way that the valveseat is soldered to the lining B up inthe neck above the bottom iiange, D, and we all know that oil of vitriolwill destroy tin or solder, and when this is gone the chamber must belined with lead. Now, in my plan, I have the lead spun of one piece, andin vsuch a way that I can turn a flange at the bottom as well as thetop, and then, having the valve-seat C, of pure lead, bolted between twotlnnges, making alead and leadjoint, with a little thin white leadbetween, I can make a chamber t'or acid free from solder, tin, or rubberjoints and burned seams where acid comes in Contact. It will be seenthat a chamber lined in this way will last i'or man v years, as the acidhas no effect on the pure lead.

I do not claim lining acid chambers or vessels with one piece ofsheet-lead, as that has been used by myself as well as others; and I donot claim wrenches and stufng-boxes, as they have been used by myself aswell as others; but

that I do claim is- 1. Making an acid chamber or vessel to hold acid fora soda-water apparatus or generators, lined with one piece ofsheet-lead, having atiange turned at the bottom as well as the top, witha valve-seat of pure lead bolted between the iange ot' the acid-chamberand the flange ot' a generator, making a chamber or vessel free from allsolder, tin, burned seams, or rubber
